When it comes to devising new ways to provide state-of-the art medical care to people living in remote areas of the world, smartphones truly are helping scientists get smarter. For example, an NIH-supported team working in Central Africa recently turned an iPhone into a low-cost video microscope capable of quickly testing to see if people infected with a parasitic worm called Loa loa can safely receive a drug intended to protect them from a different, potentially blinding parasitic disease.
As shown in the video above, the iPhone’s camera scans a drop of a person’s blood for the movement of L. loa worms. Customized software then processes the motion to count the worms (see the dark circles) in the blood sample and arrive at an estimate of the body’s total worm load. The higher the worm load, the greater the risk of developing serious side effects from a drug treatment for river blindness, also known as onchocerciasis.

Over the past year, the problem of antibiotic resistance has received considerable attention, with concerns being raised by scientists, clinicians, public health officials, and many others around the globe. These bacteria are found not only in hospitals, but in a wide range of community settings. In the United States alone, antibiotic-resistant bacteria cause roughly 2 million infections per year, and 23,000 deaths .
In light of such daunting statistics, the need for action at the highest levels is clear, as is demonstrated by an Executive Order issued today by the President. Fighting antibiotic resistance is both a public health and national security priority. The White House has joined together with leaders from government, academia, and public health to create a multi-pronged approach to combat antibiotic resistance. Two high-level reports released today—the White House’s National Strategy for Combating Antibiotic-Resistant Bacteria (CARB) and the complementary President’s Council of Advisors on Science and Technology (PCAST) Report to the President on Combating Antibiotic Resistance—outline a series of bold steps aimed at addressing this growing public health threat.
